Gauss Law: Proofs and Electromagnetism Resources

AI Thread Summary
Gauss's Law can be derived from Coulomb's Law, and it holds true regardless of charge distribution within a surface, with the relationship ø=q/ε being consistent. The discussion highlights a resource, "Introduction to Electrodynamics" by David J. Griffiths, as a recommended book for understanding electromagnetism. Participants express varying levels of comfort with the mathematical proofs, noting that while some find them complex, they appreciate that the law applies to all shapes, not just spheres. The concept of describing a Gaussian surface as a point charge is debated, with some seeking clarification on its relevance. Overall, the conversation emphasizes the foundational nature of Gauss's Law in electromagnetism.

about gauss law!

is there any precise proof for gauss law?
why ø=q/ε always regardless how the charge is distributed inside the surface
and if anyone know a good book for electromagnetism please type its name for me..
thank u

Every guassian surface can be described as a point charge. Electric field equals firce field lines per area. So the number of field lines equals e times a.
 
thank u all
SteamKing, although the proof is complicated for me (advanced calculus for my level) , i`m relieved to know at least that there is a precise proof applicable for all shapes not only spheres! so thank u again

sorry,, i don`t get what you are trying to say..
why would we describe a gaussian surface as apoint charge??
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
